96095 - EventReceiver: Entry point not found - ?GetUnicode@nsString@@QBEPBGXZ

Status: VERIFIED DUPLICATE of bug 108515

(SeaMonkey :: Installer, defect)

Description

[Jonas Jørgensen]

After installing Mozilla 0.9.3 over 0.9.2, the Mozilla splash screen appeared
for a second, and then I got the following message:

Dialog Title: "NSPR:EventReceiver: Mozilla.exe - Entry Point Not Found"
Text: "The procedure entry point ?GetUnicode@nsString@@QBEPBGXZ could not be
located in the dynamic link library xpcom.dll."

When I clicked OK, Mozilla appeared, and everything worked fine. This seems to
be  related to Bug 71010, but I'm filing this as a seperate bug as
[e-mail] suggested.

Comment 2

[K'Trina Medina]

The text in the error message windows are different. Are they all related due to
the dialog title?

This bug:
Dialog Title: "NSPR:EventReceiver: Mozilla.exe - Entry Point Not Found"
Text: "The procedure entry point ?GetUnicode@nsString@@QBEPBGXZ could not be
located in the dynamic link library xpcom.dll."

Bug 94108:
Dialog Title: "NSPR: EventReceiver: Netscp6.exe - Entry Point Not Found"
Text: "The procedure entry point
?NS_NewGenericModule@@YAIPBDIPAUnsModuleComponentInfo@@P6AXPAVnsIModule@@@ZPAPAV2@@Z
could not be located in the dynamic link library xpcom.dll.

Bug 71010:
Dialog Title: "NSPR: EventReceiver: Netscp6.exe - Entry Point Not Found" 
Text: "Entry point ??0nsInputFileStream@@QAE@ABV0@@Z could not be located in
dynamic link library xpcom.dll."

This has nothing to do with the NS_NewGenericModule problems of bug 94108. Yes,
it's probably a similar issue of not cleaning up a file, but each file we want
to remove has to be coded individually so this is not a duplicate of that bug,
anymore than forgetting to install necko2.dll is the same as forgetting to
install the mork database .dll.

I'm experiencing this as well on W2K in 2001100303 and also in yesterday's 
build it did this.

Comment 6

[Ron]

After setup completes I get this error message 

"NSPR:EventReceiver:Mozilla.exe" - Entrypoint niet gevonden
Kan entrypoint van procedure ?ToNewUnicode@nsString@@QBEPAGXZ niet vinden in
DLL-bestand xpcom.dll

Sorry for the dutch here is a rough translation:

"NSPR:EventReceiver:Mozilla.exe" - Cannot find Entrypoint
Cannot find entrypoint of procedure ?ToNewUnicode@nsString@@QBEPAGXZ in
DLL-file xpcom.dll

I'm using mozilla 0.9 trunk 2001100210, Win2k

Comment 7

[Daniel Veditz [:dveditz]]

1) what install options did you select?
2) were you installing to a fresh directory?
3) if not, what build were you installing over?

Comment 8

[Ron]

1. Install options: Complete, no quicklaunch
2. Fresh Directory ?: No
3. Previous version: 0.9.4

Comment 9

[Ron]

I just downloaded 0.9.5 and the previously reported bug still exists. Even after
an uninstall-install. 

Comment 10

[sean]

I just ran into this bug upgrading from 0.9.4 to 0.9.5.  I did a "custom"
installation, but selected everything (security manager & debugger selected in
addition to the required components; Quick Launch selected).  0.9.4 was
installed in similar fashion.  I did Exit Mozilla before running the 0.9.5
installer.  I did install over the old Mozilla, not into a fresh directory.

My error dialog said this:

NSPR:EventReceiver: Mozilla.exe - Entry Point Not Found

The procedure entry point ?ToNewUnicode@nsString@@QBEPAGXZ could not be located
in the dynamic link library xpcom.dll.

Comment 11

[Wesley Tanaka]

I ran into this bug when upgrading ("complete") from 0.9.4 to 0.9.5

My dialog box was:

---------------------------
NSPR:EventReceiver: Mozilla.exe - Entry Point Not Found
---------------------------
The procedure entry point ?ToNewUnicode@nsString@@QBEPAGXZ could not be located
in the dynamic link library xpcom.dll. 
---------------------------
OK   
---------------------------

Comment 12

[Wesley Tanaka]

is this related to bug 97435?

Comment 13

[Adam Katz]

I've found this bug rather frequently upon updating Mozilla.  I believe (though
am not 100% sure) that I get it from the nightly zips as well as nightly and
milestone installers.  The error message pops up only once, on first run, and
not again until my next update.  I run Win2k, WindowBlinds, LiteStep, and ZoneAlarm.

Comment 14

[Ron]

Acually this prevents me from upgrading at all, the new mozilla's don't want to
run after this bug appears. So I have to stick with 0.9.4 until they find what
is wrong.

Comment 15

[Daniel Veditz [:dveditz]]

Or uninstall the old one first, or install into a new directory. Upgrading on
top of an old build is not the only way to upgrade.

Is the message you get *exactly* the one in this bug? This message comes up for
a class of similar bugs, but each has to be fixed separately. It shouldn't cause
Mozilla to stop working since these messages come when old components--which
should have been deleted anyway--fail to load. Try deleting your component.reg
and starting again, and failing that install into a new directory. Please file
any deviation from the specific entry point under consideration as a new bug.

[Paul Mischler]

This bug is seemingly related to <A
HREF="http://bugzilla.mozilla.org/show_bug.cgi?id=102497">Bug 102497</A>.  I
don't feel qualified marking it a duplicate though.  There's far more on this
bug than on 102497, but there is a workaround listed for 102497.

I'm seeing the same problem with 2001100303 (I did not see this with 2001093008 
BTW). And yes when running with a new profile it goes away. And even after 
deleting the new profile, and running with the old profile still doesn't show 
up (?).

I have this bug (or at least one very similar) when I try to view plugins either
form help menu, entering about:plugins in the address bar or using
http://home.netscape.com/plugins/manager.html

I use Mozilla 0.9.5 on Windows 2000 Service Pack 1. I upgraded from 0.9.4 before
this error occured

I noticed this error after attepting to install the Java plugin - after it
installed to my machine it failed to work in Mozilla so I checekd the plugins page.

I have Java Plugin 1.3.0_01 (inslalled via Mozilla) and 1.3.1 (installed as part
of Star Office 6 Beta later)

The error message is slightly different - it reads

Mozilla.exe - Entry Point Not Found
The procedure entry point ?ToNewUnicode@nsString@@QBEPAGXZ could not be located
in the dynamic link library
xpcom.dll.

there is no mention of "EventReceiver: "

Comment 18

[Phillip A Remaker]

I have the same error, upgrading from 0.9.3 (I think) to 0.9.5 after install.

At End of install of build 0.9.5 aka 2001101117

The procedure entry point ?ToNewUnicode@nsstring@@QBEPAGXZ could not be located
in the dynamic link library xpcom.dll

Comment 19

[Lisa Lorenzin]

I have this bug on my Windoze box (running Win2k 5.00.2195 SP2).  I had Mozilla
0.9.3 installed, a custom install - everything except Mail & News and Chatzilla.
 No problems there.

I upgraded to Mozilla 0.9.5, same custom install (it didn't prompt me to reboot,
so I didn't bother), and after the upgrade, I saw an error message about Entry
point not found - ?GetUnicodesomethingorother (didn't write that one down).

I exited Mozilla (including the QuickLauncher) and restarted it, with no error.
 Worked fine until I tried Help -> About Plugins, then I got this exact error:

Mozilla.exe - Entry Point Not Found
The procedure entry point ?ToNewUnicode@nsString@@QBEPAGXZ could not be located
in the dynamic link library xpcom.dll.

Once I clicked OK, I got the plugins page.  

I upgraded to the latest nightly build (2001110903).  Again, I did a Custom
install of everything except Mail & News and Chatzilla.  Same results as above.

Comment 20

[Melissa Wilson]

I had this problem with Mozilla 0.9.5 and again today with 0.9.6, so I'm
guessing it hasn't been fixed yet. The exact error message I get on first load is

----
The procedure entry point ?ToNewUnicode@nsString@@QBEPAGXZ could not be located
in the dynamic link library xpcom.dll.
----

However, I've only gotten the error when I installed a new build over an old. 
When I uninstall the old build before installing the new, it doesn't happen.

Comment 21

[Syd Logan]

I'd sure like to not keep seeing these reports, Curt, can you get to the bottom
of this? Is the architecture for installing into a previously installed
directory flawed in some way?

Comment 22

[Daniel Veditz [:dveditz]]

This is not an installer problem, this is due to the way Mozilla development is
carried out -- old components will NOT work against a newer core.

We could go back to the "nuke from orbit" strategy currently used in the Mac and
Linux install. That would stop these problems dead, but then we'll get
complaints about zapping 3rd party stuff the user has installed.

Comment 23

[Curt Patrick (gone)]

I have a bug 101801, targeted for 0.9.8, to work on improving the installer
bulid process to capture changes in deliverables so that we can keep on top of
this problem better.  I'll move that to the top of the 0.9.8 list.

Comment 24

[Curt Patrick (gone)]

I think this has been fixed--see patch for bug 108515--but it has not been
verified/closed.  K'trina, could you let me know if this is resolved or not,
please.  Thanks.

Marking verified (see patch for bug 108515)  

Curt, I have not seen this error message recently.
